Hard-Drive Features

The C8000XD storage sled is available with 12-drive or 24-drive option. All

hard-drives are mounted in special hard-drive carriers and connect to the

hard-drive backplane inside the sled.

• Standard hard-drive carrier supports 3.5-inch SAS/SATA/SSD hard-drive.

• Flexible hard-drive carrier supports 2.5-inch SAS/SATA/SSD hard-drive.

• Expansion hard-drive carrier supports two 2.5-inch SSD hard-drives.

The 12-drive configuration installs 12 standard or flexible hard-drive carriers.

The 24-drive configuration installs 12 expansion hard-drive carriers. See

"Hard-Drive Indicator Patterns" on page 10 for information on the hard-drive

indicators on the sled. Different patterns are displayed as drive events occur

in the sled.

Hard-Drive Indicator Patterns

The C8000XD sled hard-drive backplanes include a hard-drive activity LED

and two bi-colored hard-drive status and fault LEDs per drive. The state of

the hard-drive backplane indicators alerts you to the condition of the hard-

drives in the sled. You can view the status of the hard-drive indicators on the

backplane by opening the sled (See "Opening the Sled" on page 28). The

hard-drive indicators are visible on both sides of the bottom edge of the hard-

drive cage.

The following illustrations show the location of the hard-drive indicators in a

12-drive or 24-drive bay sled.

SAS Connectors Features

The storage sled has two SASx28 expander chips on the SAS expander. Each

expander chip, labeled LSI 28 port 6 GB expander A/B port in Figure 1-8, has

its own unique SAS address and connects to two internal mini-SAS

connectors and two external mini-SAS connectors. The external mini-SAS

connectors support direct cable connection, an external mini-SAS x4 cable

(SFF-8088) connects the compute sled’s HBA/RAID card to the SAS

expander. The external mini-SAS A1, A2, B1, and B2 connectors connect to

all 12 or 24 hard-drives. The internal mini-SAS connectors support hard-drive

backplane connection, the hard-drives and SAS expander in the storage sled

communicates via the hard-drive backplane.

The storage sled includes an Expander Flash Utility (Xflash). This utility is a

Windows or Linux-based command line utility that you can use to identify

the SAS address of the SAS expander, determine the expander firmware

version, reset the SAS expander, or upgrade the firmware on the SAS

expander chips. See "Using the Expander Flash Utility" on page 59 for more

information about the expander flash utility.

NOTE: When you configure zoning for the storage sled, the external mini-SAS

connectors are separated into zone groups 0, 1, 2, and 3. Zoning allows each

compute sled to have access to the hard-drives in an assigned zone.

Expander Configuration Mode

The C8000XD sled is equipped with a SAS expander to operate the hard-

drives in single port, dual port, or expansion mode. Use mini-SAS x4 cable(s)

to connect a compute sled to your C8000XD sled.

The sled supports the following configuration modes.

•Single port mode

In single port mode, the storage sled supports 12 x 2.5 or 3.5-inch

SAS/SATA/SSD hard-drives from a single cable connection.

The figure below shows a single path connection from a single-HBA/RAID

compute sled to the storage sled’s external mini-SAS A1 and A2

connectors. In this mode, the hard-drives in the storage sled are cascaded

for extended storage capacity.

About Your System 17

The figure below shows a single path connection from single-HBA/RAID

compute sled to two cascaded storage sleds. In this mode, the hard-drives

in the two storage sleds are cascaded for extended storage capacity.

•Dual port mode

In dual port mode, the storage sled SAS expander board supports 12 x 2.5

or 3.5-inch SAS hard-drives from a dual-cable connection.

The figure below shows a dual path connection from a dual-HBA compute

sled connected to the storage sled’s external mini-SAS A1 and B1

connectors. This mode delivers dual path functionality and redundant

path capability.

About Your System 19

• Expansion mode (non-zoning)

In expansion mode, the storage sled SAS expander board supports 24 x 2.5

SSD hard-drives from a dual-cable connection.

The figure below shows a dual path connection from a single-RAID

compute sled connected to the storage sled’s external mini-SAS A1 and A2

connectors. In this mode, the hard-drives in the storage sled are cascaded

for extended storage capacity.

20 About Your System

• Expansion mode (four zones)

In expansion mode with four zones configuration, the storage sled SAS

expander board supports 24 x 2.5 SSD hard-drives from a single-cable

connection. The SAS connections are grouped into four zones (A1/Zone 0,

A2/Zone 1, B1/Zone 2, B2/Zone 3) and each zone allows the host/compute

sled to access a group of hard-drives in the storage sled.

The figure below shows four single-RAID compute sleds connected to the

storage sled’s four external mini-SAS connectors. Each compute sled can

only access the hard-drives in the assigned zone.
